MARSHALL H. MALLORY, OF NEW YORK, N. Y.

TH EATER-STAG E.

SPECIFICATION forming part of Letters Patent No. 228,468, dated June 8, 1880.

Application filed February 21, 1880.

To all whom it may concern:

Be it known that I, lVIARSHALL H. MALLORY, of the city of New York, county of New York, State of New York, have invented a new and useful Improvement in Theater-Stages, which is fully set forth in the following specification and accompanying drawings, in which 7 Figure 1 is a front view of my improved stage; Fig. 2, a plan of the same, and Fig. 3 a side view thereof.

The object of my improvement is to facilitate the speedy representation of the successive acts or scenes of a play by means of what are called double stages, upon one of which the scene next to appear may be'set while the preceding is being given.

Heretofore thishas been accomplished by having two movable stages, one above the other, which necessitates deep excavation and high walls, always attendant with considerable expense, and in some 'localities with very great expense, while in others it is almost impracticable with any outlay.

l obviate these serious objections and difficulties by constructing two or more complete movable stages, side by side on the same plane, and mounting them on cannon-balls, or with such appliances as admit of their ready removal sidewise or forward and back, in tracks provided for such transit.

A is the proscenium-opening; B B, the movable stages- Q, the floor-pt themaiu stage; D, the tracks therein; E E, the balls or other means of transport.

The tracks, as represented, are at right angles, but the track-lines may be "aried to accommodate the space or construction of different theatres; withoutdeparting from the principle or leading idea of my improvement, which is to provide for the read y'transition of a stage from the proscenium-openiug to some other place, and admit of another stage to succeed it, to be followed by the previous stage or another at pleasure.

What 1 claim as my invention, and desire to secure by Letters Patent, is-

Two or more movable stages on the same plane, in combination with a main stage, provided with tracks by which ouestage may be removed from the proscenium-opening and another substituted therefor.

MARSH ALL H. MALLORY.
